As a result of the country’s online censorship, many citizens and visitors have turned to Virtual Private Networks (VPNs) as a means to access the sites and content that have been banned by the government. Today, several companies have reported receiving notifications from Apple stating that their Apps have been pulled from the Chinese store.

ExpressVPN wrote in a blog post that Apple explained that its products violated Chinese law, and said that they found that “all major VPN apps for iOS ave been removed” from the store. Another company, Star VPN, also reported receiving the notice.

ExpressVPN said that it was disappointed to see Apple “aiding China’s censorship agents,” and condemned the removals. The country appears to be pushing back against the usage of VPNs, launching a campaign to block companies from setting up or renting out such networks without official approval earlier this year. Some users — those who have a billing address outside of China — can still download the apps from the App stores from other territories.

We’ve reached out to Apple for comment, and will update if we hear back.
